Features and Benefits:
Rytons A1® Fire-rated Round FlowRyt® Grilles with Spigots
General Details
- A range of three round metal grilles with spigots.
- Manufactured from A1 classified galvanised steel.
- FlowRyt® design provides a high air flow whilst maintaining low resistance.
- Wide flange covers cut edges to maintain a neat appearance in cladding.
- 50mm deep spigot provides a positive attachment for ducting.
- Supplied custom powder coated to Class A2-s1, d0. Choose from the RAL Classic colour chart in matt, semi-gloss or gloss finishes to match cladding or brickwork. Signature architectural finishes are also available.
